Conversion Formula
The conversion formula from bar to psi is: psi = bar × 14.5038. This works because 1 bar equals 14.5038 psi, a fixed standard derived from the definition of the units. For example, to convert 0.5 bar: 0.5 × 14.5038 = 7.2519 psi. This simple multiplication allows quick conversions without complex calculations.
Conversion Example
- Convert 0.5 bar to psi:
- Start with 0.5 bar.
- Multiply by 14.5038.
- 0.5 × 14.5038 = 7.2519 psi.
- Convert 1 bar to psi:
- Use 1 as the initial value.
- Multiply by 14.5038.
- 1 × 14.5038 = 14.5038 psi.
- Convert 2.5 bar to psi:
- Start with 2.5 bar.
- Multiply by 14.5038.
- 2.5 × 14.5038 = 36.2595 psi.
- Convert 0.75 bar to psi:
- Begin with 0.75 bar.
- Multiply by 14.5038.
- 0.75 × 14.5038 = 10.8779 psi.

Conversion Definitions
Bar
A bar is a metric unit of pressure equal to 100,000 pascals, roughly the atmospheric pressure at sea level. It measures force per unit area, used in science and engineering to quantify pressure in various applications including weather and industrial systems.
Psi
Pounds per square inch (psi) is a pressure measurement unit used mainly in the United States, representing the force in pounds applied over an area of one square inch. It’s common in automotive, manufacturing, and HVAC systems to indicate pressure levels.
Conversion FAQs
Why does 0.15 bar equal about 2.1772 psi?
This is because 1 bar equals exactly 14.5038 psi, so multiplying 0.15 by that number gives the pressure in psi. The fixed conversion factor allows precise translation between these units, making calculations straightforward.
Can I convert bar to psi manually for any value?
Yes, by multiplying the number of bar by 14.5038, you can convert any pressure measurement from bar to psi. This method applies universally, regardless of the specific value, as long as you use the correct conversion factor.
What is the significance of using 14.5038 as the conversion factor?
This number is derived from the definition of the units: 1 bar equals 100,000 pascals, and 1 psi equals 6894.76 pascals. Dividing 100,000 by 6894.76 results in approximately 14.5038, establishing the conversion rate.
